Value Collection HC1008070-050BX M8 Hex Cap Screw Din 931

Product Description

The VALUE COLLECTION HC1008070-050BX is a metric hex head cap screw engineered for high-strength fastening applications across industrial, mechanical, and structural assemblies. Sized at M8 x 1.25 with a 70 mm length under head, this screw is partially threaded per DIN 931, which allows the unthreaded shank to bear shear loads without thread engagement in the joint. Manufactured from Grade 10.9 steel and finished with a black oxide coating, it delivers reliable clamping force and moderate corrosion resistance in a compact hex-drive profile. The 13 mm hex size fits standard metric wrenches and sockets for fast installation.

This screw is suited for machinery assembly, automotive drivetrain and chassis work, industrial equipment maintenance, and general metalwork requiring a high-strength metric fastener. The partially threaded shank makes it especially appropriate for bolted joints where the fastener passes through a clearance hole before threading into a tapped bore or nut. Commonly installed by machinists, maintenance technicians, and automotive mechanics in both shop and field environments.

Key Features

• Grade 10.9 steel construction for high tensile and proof load performance
• Partially threaded shank per DIN 931 for shear-bearing bolted joints
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• M8 x 1.25 metric thread pitch compatible with standard metric tapped holes and nuts
• 13 mm hex drive fits common metric wrenches and impact sockets
• 70 mm length under head suits medium-depth fastening applications

Compatibility

Designed as an OEM-style replacement or standard-service fastener for any application requiring a DIN 931 partially threaded metric hex head cap screw in M8 x 1.25 x 70 mm, Grade 10.9.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with metric fastener torque specifications for Grade 10.9 hardware. Always verify that the mating tapped hole or nut matches the M8 x 1.25 thread pitch before driving the fastener. Use a calibrated torque wrench and apply the torque value specified by the equipment manufacturer for the joint being assembled. Inspect threads for damage or contamination before installation and replace any fastener that shows signs of deformation.
